Golfballs.com Expert Description

Fast, long, and forgiving, the Callaway Golf Big Bertha OS Steel Irons incorporate advanced technology to provide players with the distance and speed their games crave. Repositioned weight thanks to the Exo-Cage enhances forgiveness, while 360 Face Cup design boost ball speed for faster and more powerful plays, even when they’re off center. Comes standard with a True Temper Speed Step 80 shaft that’s ideal for players with faster swing speeds who want more feedback.

Improved Forgiveness and Speed

Thanks to the incorporation of the all-new super light yet incredibly strong Exo-Cage, the Big Bertha OS Irons can shift more weight to strategic locations of the club head in order to enhance forgiveness. The relocation of weight also helps the 360 Face Cup technology by pushing COR to the legal limit, and producing impressive ball speeds for outstanding distance.

High Launch and Long Carry

With the inclusion of tungsten-loaded Standing Wave technology in the sole, these irons are able to achieve progressively lower centers of gravity optimized for each club in the set, from the highest-loft down to the lowest-loft. A raised launch angle in the long-irons pushes shots farther, while the launch angle of the short-irons helps golfers achieve more control.

Features of the Callaway Golf Big Bertha OS Steel Irons:

More forgiveness and ball speed from new exo-cage technology

Even more ball speed from next gen 360 face cup

Higher launch for longer carry from tungsten-loaded standing wave

Progressive center of gravity for increased control
